What is 100% Wool? Why You Should Care About Natural Fibres

Explanation of a natural textile with centuries-old applications in clothing, blankets and historical outfits

Introduction

Wool is one of the oldest textile types in the world and has been used for clothing for thousands of years. When a product is labeled as 100% wool, it means the fabric is completely made of wool fibers, without the addition of other materials. This affects comfort, durability, maintenance and historical appearance.

Historical & cultural context

Wool has been used since prehistoric times. In Europe, traces of wool processing have been found dating back to around 3000 BC.
In the Roman era (ca. 0–400 AD) wool was the most commonly used textile for tunics, cloaks and military clothing. It also remained dominant throughout the Middle Ages (ca. 500–1500), mainly because it was warm, sturdy and easy to dye.

Until well into the 19th century, wool was considered one of the most important raw materials for everyday clothing, uniforms and blankets.

What does 100% wool mean?

A 100% wool product consists entirely of wool fibers, usually sourced from sheep. No other fibers have been added, such as synthetic materials or plant-based fibers. This ensures that all the natural properties of wool are retained.

With wool blend materials are often added to reduce costs or simplify maintenance. With 100% wool, that is not the case.

Properties of 100% wool

Heat regulation

Wool insulates excellently while remaining breathable. It retains heat when it's cold and releases excess heat when temperatures rise.

Protection from the sun

Because wool remains breathable, it protects not only against cold but also against overheating from the sun.

Moisture absorption

Wool can absorb a large amount of moisture without feeling wet. This keeps it comfortable in rain, mist or perspiration.

Natural and sustainable

Wool is a renewable resource and biodegradable. With proper care, woolen clothing lasts for years.

Appearance and structure

100% wool has a natural, often matte appearance. The fabric can feel sturdy or slightly rough, depending on the weave and quality of the wool.

Difference between 100% wool and wool blend

With 100% wool, the fabric consists entirely of natural wool fibers. This makes the material breathable, insulating and historically accurate.
Wool blends contain other fibers besides wool, such as synthetic materials. These fabrics are often easier to maintain, but lack some of the natural properties of wool. A good combination of wool blend keeps the garment lower in price while maintaining the high-quality nature of wool.

Practical tips for use

Application

100% wool is widely used for:

  • Cloaks and capes

  • Tunics and dresses

  • Trousers

  • Blankets and plaids

Maintenance

Wool requires careful maintenance:

  • Hand wash or a special wool wash program

  • Use of wool detergent

  • Do not wring or wash in hot water

  • Dry flat

Improper washing can lead to shrinkage or felting.

Closing

100% wool is a natural, sustainable and historically accurate material with excellent insulating and breathable properties. While it requires a bit more maintenance than modern fabrics, it offers comfort, durability and an authentic appearance that perfectly suits historical clothing and roleplay.

Use this knowledge to consciously choose materials that match your outfit, period and use.
